Power System Directory Services System Design And Realization

Directory service is a system which provides query and management on shared information. Different from traditional system which based on Web and relational databases, directory service is more suitable for frequent read, but less write applications. It is one of the basic applications of the next generation of Internet service. Directory service provides a more effective and convenient way for user to manage and access network resources, and also have more favorable conditions and more sophisticated technology for the application system management and resource integration of modern enterprises. Using directory service can greatly simplify the management of network resource and improve the utilization of network resources.The basic knowledge and some basic design principles of directory service are described firstly in this thesis, and then proposal and development of directory service are introduced, as well as its communication protocol and related RFC standards. From the third chapter on, from the perspective of software engineering, the design and implementation of directory service are presented, mainly focusing on data synchronization, the basis of directory services. In the fourth chapter, detail of the design and implementation of data synchronization is also illustrated. Finally, summary of the design and implementation of this project and some analysis of the prospects of directory system are given.
